Diastereomers: Are stereoisomers that are not

Diastereomers are stereoisomers that are not mirror images of each other and have different physical and chemical properties. Diastereomers are defined as compounds which have the same molecular formula and sequence of bonded elements but which are nonsuperimposable, non-mirror images. Learn what diastereomers are, how they differ from enantiomers and geometrical isomers, and how to identify and separate them. See examples of diastereomers with two or more stereocenters and their physical and chemical properties. Diastereomers are two molecules which are stereoisomers (same molecular formula, same connectivity, different arrangement of atoms in space) but are not enantiomers.
